# What is the meaning of “load case consistent” in stress analysis terms?

I’m a (junior) stress engineer and have been tasked with sizing a lug. Various loadcases have been run through FEM and loads have been distributed into the lug bolt for each. In other words, each loadcase has its own set of x, y, and z loads at the bolt.

An initial analysis (spreadsheet) was run, where the lug was sized using the max x, y, and z loads across all loadcases. My understanding is that this is conservative.

Now I’m being asked to take out conservatism by applying case consistent loads. Would I go about that just by doing an analysis for each loadcase with a max value? Am I understanding the meaning of “case consistent”?

As an example:

Loadcase 1 has no maxes, so I don’t even look at it

Loadcase 2 has the max x, so I analyze the lug using all values from this loadcase

Loadcase 3 has no maxes, so I don’t even look at it

Loadcase 4 has the max y, so I analyze the lug using all values from this loadcase

Loadcase 5 has the max z, so I analyze the lug using all values from this loadcase

Sorry for the long post, but any help is appreciated.

• Could it mean no cyclic loads? Why not sk the person who gave you the instruction - it came from somewhere. – Solar Mike Jul 9 at 7:21
• @SolarMike I’d love to ask the person who gave me these instructions, but unfortunately they’re located out of my country and their email server is down... – Hunter Jul 9 at 16:33
• Then apply some commonsense and think about the assumptions you might make. – Solar Mike Jul 9 at 16:40
